Title:

BLOCK COPOLYMER COMPOSITION AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/103102

Kind Code:

A1

Abstract:

Provided is a block copolymer composition which includes a block copolymer having a specific molecular structure, and has a molecular weight distribution with a suitable range. The present invention obtains a block copolymer composition containing a block copolymer in which all of the block structural units are derived from vinyl monomers and at least one block has a branched structure, the block copolymer composition being obtained by polymerizing: a polymerizable composition containing a macromonomer (A) having a group with a radical-reactive unsaturated double bond on one end of a poly(meth)acrylate segment, a vinyl monomer (B), and an organic iodine compound (C); or a polymerizable composition containing the macromonomer (A), the vinyl monomer (B), an azo radical polymerization initiator (E), and iodine.
